USAD had a video tape about it a few years back. You try to construct something that works like a wetlands area in a small area letting the water move slowly thru a series of areas where various biological and filtering processes can work on it. It will be good at removing most organic pollutants (some really exotic ones may need special treatment). Heavy metals and really strange organics should be kept out of waste streams in the first place as they greatly increase the cost of handling those waste streams compared to the cost of handling the exotics separately.
